1. What is Fuel Injector Conversion?

Fuel injector conversion calculates the equivalent size when converting between different measurement units (typically lb/hr to cc/min or vice versa) for fuel injectors. The standard conversion factor is approximately 10.5 (1 lb/hr ≈ 10.5 cc/min for gas).

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( old\_size \) — Original injector size (lb/hr or cc/min)
• \( factor \) — Conversion factor (typically 10.5 for lb/hr to cc/min)

Explanation: The equation provides a straightforward way to convert between different fuel injector sizing units.

3. Importance of Conversion

Details: Accurate conversion is crucial when comparing injector sizes, upgrading fuel systems, or working with engine management systems that use different measurement units.

4. Using the Calculator

Tips: Enter the original injector size in either lb/hr or cc/min, then enter the appropriate conversion factor. The standard factor for lb/hr to cc/min is 10.5.

5. Frequently Asked Questions (FAQ)

Q1: Why is 10.5 the standard conversion factor?
A: This factor is based on the density of gasoline and provides a practical approximation for most automotive applications.

Q2: Does this work for diesel injectors?
A: The factor may vary slightly for diesel due to different fuel density, but 10.5 is still commonly used as an approximation.

Q3: How accurate is this conversion?
A: It provides a good engineering approximation, but actual flow rates can vary slightly based on specific fuel properties and injector characteristics.

Q4: When would I need to convert injector sizes?
A: Common scenarios include comparing injectors from different manufacturers, tuning ECU parameters, or upgrading fuel systems.

Q5: Are there other conversion factors?
A: Some applications may use slightly different factors (e.g., 10.2 or 10.6) based on specific fuel properties or measurement standards.
